[CMake] Compile/install on HPUX on ia64 (Itanium)

[David Akdikmen]

Hi,

What version of the compiler you got?  I'm getting all sorts of problems
now trying to build ITK with the cmake I made from the CVS tree.  My new
Itanium has been commandeered as the new Sub-version server and this old
box I'm using has HP ANSI C Version A.05.50 [September 03].  Notice that
there are 4 newer versions available from HP, A.05.55, A.05.60, A.06.05,
and A.06.10. 

I have general question on how cmake works, does it take the compiler
and options you specify in the CMakeCache.txt file and test to see if
various headers and feature exist with that compiler/options or does it
look when it was being created?  Or does it just look for the header
files?  Or some mixture of some "built-in settings" and others tested?

I tried setting the "-AP" compiler option in the CMakeCache.txt, which
disables <iostream> and re-enables <iostream.h>, but the configurations
still says it detected support for the new style IO streams?

My HP does this:


Performing C SOURCE FILE Test ATTR_UNUSED_VAR succeded with the
following output:
gmake -f CMakeFiles/cmTryCompileExec.dir/build.make

  int main() { int x __attribute__((__unused__)) ; return 0; }
                                                              ^

The problem seems to be that the file should have a newline on it. 
We have checked in a change to the source to put the newline in the
file.
